Final answer:
To estimate the population proportion from a dotplot, count the number of successes and the total sample size. Divide the number of successes by the sample size to get the estimated population proportion.
Step-by-step explanation:
To estimate the population proportion from a dotplot, you need to count the number of successes and the total sample size. Let's say the dotplot shows the proportion of students who passed a test out of a sample of 100 students. If there are 65 dots representing students who passed, the estimated population proportion would be 65/100, or 0.65. This means that approximately 65% of the population passed the test.
